BRENTWOOD, N.H. (CBS/AP) — A police officer was shot and killed at a home in New Hampshire just before a fire and explosion destroyed the home Monday afternoon, authorities said.

The shooting and explosion happened in a suburban duplex home in a 55-and-up community on Mill Pond Road in Brentwood shortly after 4 p.m. Police were called to the home after a domestic dispute.

Authorities identified the officer who was shot and killed as 48-year-old Steve Arkell.

The suspect, 47-year-old Michael Nolan, is believed to have died in the fire.

After the blaze started around 4 p.m., firefighters were kept away from the scene. Within minutes of the explosion, the house was engulfed in flames as black smoke billowed over the neighborhood.

After firefighters started attacking the blaze around 6 p.m., the fire was largely knocked down about a half hour later and it didn't appear to have spread to neighboring houses.

Public records indicate the house was owned by 86-year-old Walter Nolan.

Arkell was a 15-year veteran of the Brentwood, New Hampshire police department and a father of two.

New Hampshire Governor Maggie Hassan issued the following statement and directed flags to half-staff in honor of fallen Brentwood Officer Steve Arkell:

"The entire State of New Hampshire is in mourning over the tragic loss of Brentwood Officer Steve Arkell. Officer Arkell bravely answered the call of duty and made the ultimate sacrifice, a heroic demonstration of his commitment to the safety of his fellow citizens. Like so many of our first responders do on a daily basis, Officer Arkell courageously put his life on the line to protect others, and in doing so, was tragically taken far too soon.

"It is now the responsibility of all Granite Staters to honor Officer Arkell's sacrifice by coming together and doing everything that we can to support those he has left behind. My thoughts and prayers are with his family and loved ones, as well as everyone in Brentwood and the surrounding communities affected by this horrific tragedy."
